SPECIFICATION forming part of Letters Patent No. 285,330, dated September 18, 1883.

Application filed March 29, 1888. 4(No model.) i

To all whom it may cancern:

Be it known that I, VILLIAMJ. WILKns, of Chicago, county of Cook, and State of Illinois, have 'inVented certain new and useful Improvements in' Grain-Binders, of which the following is a full, clear, and exactl description, that will enable others to understand and make use of the same, reference being had to'the accompanying drawings, and to letters of reference marked thereon, forniing a .part of this specification.

` This inVention relates to improvements i na tying mechanism for grain-binders; and it consists, first, of means for' transmitting motion from the main shaft of the Operating mechanism to the oord-clamping disk; second, of means for clamping the cord in relation to the clamping-disk, and finally the arrangement of a knife for seVering the bindi'ng-cord, all as will be hereinafter more fully set forth.

Figure 1 is a top View of the frame or bracket supportingthe tying mechanism embodyingi A2, which is an integral part of the tyer-frame;

A3, the hub carrying the discharge-arin At 1 The hub A3 is provided with a projecting collar or sleeve, as indicated by the dotted lines in Fig. l of the' drawings, which telescopes with the hubof the segmental gear-wheel B', to which it is adjustably secured by the setscrew a, and rotates simultaneously with the hub A3, carrying lthe discharge-arm, which is secnredto the shaft'A' by means of the setscrcw a'. The gear-wheel B' has a dish-shaped rim, as shown, and is provided with a segment series of teeth, (L2, arranged at one point on the inner dished surface of the rim and set at the proper angle to adapt them to engage with the beVeled pinion B2 located on one end of the diagonal shaft B3. The dish-shaped rim of the gear-wheel serVes to retain the pinion BZ in proper relatiVe positiowwhen not in ment the required motion is transmitted to the cord-holding disk D placed on the upper end of the shaft C'.

The device for clamping the binding-cord at the proper moment consists of the plate C2,

the rear end of which is fnlcrumed at a3 and is secured to the tyer-frame by the adjustingscrew ci, as shown in Fig. 2 of the drawings, by which means the tc-nsion of the' clamping-plate may be conveniently regulated as circumstances may require. The inner edge of the clamping-plate bearing against the collar or enlarged part b of the shaft O' is curved, as indicated by the dotted lines in Fig. 2 of the drawings, to correspond to the circular form of the cord-holding disk D, the bindingtwine being clamped between' the upper side of the plate and the under side of the disk D. The disk D is rigid on the shaft O' and'is pro- Vided with four U-shaped notches b' placed at equal distauces apart in the periphery of the same. These notches catch and hold the binding-cord as 'the disk rotates and carry the cord along until it is grasped by the knottinghooks E.

The back end of the curved cutting-knifeF, indicated by dotted lines in Fig. 1 of the drawings, is pivoted to a part of the bracket under the knotting-hooks, while the opposite loose end is bent around and lies fiat on top of the disk D. The upper end of the shaft O' is of a square form, having the rounded projecting corners bz, which are adapted to be brought successively in contact with the loose end of the knife F and force the same in the opposite ing a shearing cut.

with the rounded eorners in regular order of' suceession, to meet the binding-cord as it is carried toward the knife by the disk D. The loose end of the knife F is retained in close contact with the upper end of the shaft O' by reason of the frictional contact or bearing on the upper side of the disk D;

By means of the gear-wheel B', which is adapted to have an independent adjustment by simply adjusting the set-screw which se cures it to the hub A, the eord-disk D may be accurately set, so as to bring the cord in contact with the cutting-knife at the proper time for severing` the same, which is when the knot is completed and cord is strained taut by the knottinghooks on the one side and the clamping-piate on the other.

The construction and operation of the knotting-hooks ID, and the mechanism for transmitting motion to the same are not new or original with me; but are the same as shown in other machines. Therefore a general and detailed description thereof is omitted.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is;-

1. In a grain-binder, the combination, with a segmental gear-wheel carried by and adapted to have the described adjustment relative to the main shaft of the knotter mechanism, of the pinion B2, adapted to engage with said gear-wheel, the shaft B, the pinion B4, the bevel gear-wheel O, and the shaft C', whereby moton is transmitted to the cord-clamping disk, substantiaily as described.

2. In a grain-binder, the combination7 with the cord-elamping disk D, provided with a number of notches in the edge of the same, of the shaft O, the upper end thereof being of a square form provided with rounded projecting corners, and the curved knife F, having one end pivoted to the bracket while the opposite loose end projects over on the top of said disk, and is adapted to have frictional 'contact with said disk, and to be struck by the rounded corners of said shaft, whereby said knife is intermit-tingiy moved forward to meet and sever the binding-cord, which is carried toward the same by the rotating disk D, substantially as described. r
